York, and JOHN W. RAPP,'a citizen of the' United States, and a residentof Flushing, in the borough of Queens and State of New York, haveinvented certain new and useful Improvements in Metal Window Frames andSashes, of which the following is a specification. a

This invention relates to a metal window frame and window sash, andmeans for hanging the same.

We will describea preferred embodiment of our invention and then pointout the novel features in claims.

In the accompanying drawings, in which similar reference charactersdesignate corresponding parts throughout the several views, Figure 1 isa transverse sectional view through the side of a frame and the stilesof sashes embodying our invent-ion; Fig. 2 is an enlarged verticalsection of the I upper left hand corner of one sash; Figs. 3

and 4 are details of the rollers and connections; and Fig. 5 is a detailof the means for securing the sash to the chain and weight.

, Referring now to the accompanying drawings, B designates a side of awindow frame of sheet metal construction. The casing is so formed as toprovide tracks 6 b respectively located-in position to co-act withrollers 6 carried by the upright or stile members of the respectivesashes E E. As

illustrated, the sides B of the frame are formed of a weight inclosureor pocket 6 comprising a hollow rectangular casing, the inner side facesb of which are'preferably 40 formed of separate pieces of metal suitablysecured to the balance of the weight inclosure.- As shown,'two outwardlyprojecting tracks I) b are formed in each of such side faces, upon whichtracks the grooved ,rollers e are adapted to run when the sashes aremoved. The inside and outside trim or -moldings are preferably securedto these inner side faces, which are provided with laterally extendingportions for this purpose.

' Also secured to such inner side faces I) is a and move. when thesashes are raised or and run on-the tracks b b lowered, thus formingcombined weather st-rips,'guides and dividing strips.

The vertical members or stiles and the transverse or rail members of thesashes -E E are each preferably formed of one piece of metal bent asshown. The said st1le members are preferably of the U-shape best shownin Fig. 2 and the rail members of the form best shown in Fig. 3.

The grooved rollers e are secured within the U-shaped stile members ofthe sashes Four of such rollers are preferably provided for each sash,two on each side, located respectively above and below the transversecenter line thereof, so as to prevent jamming and pinching. Each of therollers e, as shown, are

loose upon'a shaft or axle (2 having squared ends e movable backward andforward in slots e formed in bearing plates or standards e integral witha base plate 6 secured to the sash. Such rollers are nor- I mallypressed forward into contact with the tracks 6 b by a spring a The stilemembers of both sashes and the bottom rail .of the lower sash arepreferably reinforced, as shown, at suitable points by.

' The button f is passed through a hole g in a bracket plate G and thenmoved upwardly so that the shank portion of such button, which is simplya rivet or bar, fits into a contractedslot 9 leading from the hole 9upwardly, and the plate G is engaged and held between the last link ofthe chain and the enlarged head of the button f, thus form'- ing a readymeans of attachment and holding the, sash firmly. 1

Having described our invention, we claim:

1. The combination with a .pulley stile provided with tracks, of a sash,roller bearing plates secured to the sash and having horizontal slots,rollers mounted to have backward and forward movement in. the slots.

2. The combination with a pulley stile provided with outwardlyprojecting tracks,

of a sash, roller-bearing plates secured to.

the sash and having horizontal slots, grooved rollers mounted to havebackward and forward movement in the slots, and a spring for pressingthe rollers into engagement with the tracks.

3. The combination with a pulley stile provided with tracks, of a sash,roller bearing plates secured thereto and projecting laterallytherefrom, rollers mounted in said plates to have inward and outwardmovement, and springs for normally pressing the rollers to their outwardpositions.

In witness whereof, we have signed our 15 names to the foregoingspecification in the presence of two subscribing Witnesses.
